Enercorp Instruments Ltd. Solid Core Current Switch Sentry 250

Setpoint Current Operated Solid State Sensors AC or DC Loads. Solid Core Current Switch Sentry 250 is an adjustable setpoint current operated solid state sensor which monitors currents from 1 to 150 Amperes and switches up to 135 volts AC or DC. Internal circuits are totally powered by induction from the line being monitored. Solid Core Current Switch Sentry 250 design enhancements offer zero off-state leakage in the solid state relay output while switching both AC and DC circuits. The contact is not polarity sensitive, simplifying wiring.
